Good afternoon, i.
I agree that the two sides like to play with one another. Here, I'm limited by my own technological inexpertise. There are certain visual things which I can envisage, but lack the knowhow to put into effect. Perhaps one day I will remedy this nohow.

Two entities? I don't know if they are or not. I've been wondering lately if there aren't more than two parts to my own brain, anyway. Alien hand syndrome I had not heard of in that phrase though I was familiar with the idea/thought/thing behind it.

Flip-flopping between brainstates. Very interesting stuff, though not really quantifiable in any way. The flip-flopping is more of a right brain kind of idea.
